We have successfully extracted ultra-cold neutrons (UCN) from a converter volume filled with superfluid helium. This window free extraction permits high precision experiments with UCN at room temperature and in vacuum. This talk will present recent results obtained at the Munich research reactor and give an overview of the source development project at the Institut Laue Langevin.
